Our lab is interested in correlating essential genes with cosmids located on chromosome III. To this end we have rescued a number of essential genes using transformation rescue in the area covered by sDf 125 and sDf 127 (Janke et al 1997). We reported in this paper that
let-767 was rescued by cosmid C31H11. Further rescues have localized
let-767 to C56G2.6 which overlaps with C31H11. It is 55% similar to human estradiol 17-b dehydrogenase 3 over 239 amino acids.
